A burnt-out car has been recovered by detectives investigating a pre-Christmas gun attack on a police station in Fermanagh.
Dissident republicans opposed to the peace process are prime suspects after shots were fired at Lisnaskea barracks, close to the border with the Republic, on December 23.
The attack took place around 8.10pm with the shots believed to have been fired from the Castlebalfour Road area of the town.
Several rounds struck the rear of the station but nobody was injured, a spokesman for the PSNI said.
Investigators believe a grey or green Volkswagen Passat was used by the gang.
Shortly afterwards police received a report of a saloon-type car on fire in the Moher Road area off the Swanlinbar Road in nearby Kinawley.
A spokesman said: “Officers have since recovered the vehicle and are investigating a link between this car and the attack on the station.”
Republican extremists have ramped up their efforts in recent weeks, with a series of attempted bombings and gun attacks on police.
Several members of the RUC and army were targeted by terrorists in the Lisnaskea area at the height of the Troubles.
The latest Lisnaskea attack was widely condemned at the time by both unionist and nationalist politicians.
DUP MLA Arlene Foster said those responsible had nothing to offer society.
“At a time when everyone practically in our community is focused on Christmas being a time of peace and goodwill, they were trying to perpetrate evil and maim anyone possible,” she added.
Tom Elliott said he was thankful no one was injured. The UUP MLA called the shooting a “ruthless act of terrorism” and said: “Once again republican terrorists have shown that they have nothing to offer the people of Northern Ireland, but pain and suffering.”
Deputy First Minister Martin McGuinness of Sinn Fein described the shooting as a “stupid, dangerous and futile act”.
Secretary of State Theresa Villiers said: “Terrorist attempts to kill and injure people will not succeed in forcing Northern Ireland back to its past. The overwhelming majority have chosen the democratic path and totally reject violence as a means to further political aims.”
Irish foreign affairs minister Eamon Gilmore said it was a “deplorable attack by terrorists”.
